APPARATUS FOR COOLING BEER.

SPECIFICATION forming part of Letters Patent No. 394,921, dated December18, 1888.

Application filed July 13, 1887. Serial No. 244,155. (No model.)

To aZZ whom it may concern,.-

Be it known that I, ALBERT I-IALLOWELL, a citizen of the United States,residing at Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a new and useful Improvement in Apparatusfor Cooling Beer and other Substances, of which the following is aspecification.

My invention relates to that class of beercoolers where hot wort iscooled by being sprayed into the atmosphere or submitted when in afinely-divided state to the action of air; and its object is to providea more satisfactory and less expensive apparatus than has hitherto beenavailable for the purpose of carrying on this process.

My invention is illustrated in the accompanying drawings, in which--Figure 1 is an elevation, partly in section, of a portion of awort-cooling apparatus, showing the manner in which a number of sprayingdevices may be attached to a single pipe and simultaneously controlledat a single point. Fig. 2 is an elevation, partly in central verticalsection, of one of the spraying devices shown in Fig. l, showing therack and the support therefor, which is there illustrated as being usedto adjust the position of the spraying-cone of the device, and is theview seen when looking to the right at the line a b in Fig. 1. Eig. 3 isa plan of the ring at the bottom of the spraying device, and whichserves to support the spraying-cone. Eig. a is a view of a portion ofthe rack that is sometimes used to adjust the position of thespraying-cone. Fig. 5 is a plan of a ring which is sometimes claspedaround the main cone-support, formin therewith an air-chamber. l; is anelevation ol' a piece that I sometimes use to clamp upon 'therack-carrying rod to limit its motion in one direction. Fig. 7 is asection at the line c d of the cross-bar of the spraying-conesupporti11g-ring.

Similar reference-uuml)ers rcler to similar parts in all of the views.

I make use in my invention of the wellknown principles that evaporationtakes place very rapidly among very line particles of Vliquid 'whenfreely exposed to the air, and that in consequence of this evaporationlarge quantities oit' heat are absorbed in changing the liquid to vapor.This heat may be absorbed both from the unevaporated liquid and from thesurrounding air, in which case the temperature of both is lowered in theoperation. It is well known that this evaporation ceases when a certaindeiinite amount of vapor has been absorbed by a given volume of air, andthat in order to make the operation continuous it is necessary to allowa free access of unsaturated air to the spray that is produced or toremove from the surrounding air the vapor that is produced. Fresh andunsaturated air may be provided in making Ause of my invention in any ofthe usual Ways which have been hitherto adopted-such as placing thespraying apparatus in the open air or in a space freely communicatingtherewith when the liquid only is to be cooled, placing' it in a chamberinto which air is forced by a fan, or by placing it in a chamber throughwhich air is drawn by a fan or other equivalent means, since myinvention relates more especially to the means of producing the spray. Isometimes, however, make use of a special means, hereinafter set forth,of supplying a portion of the requisite air to the apparatus.

The sprayingl device here illustrated may be used either singly or inconnection with others of the same construction, as shown in Fig. 1, andan important element in its construction is that which provides means ofadjusting from a distance the position of the lsprayf'producin. cone,although this element may in some cases be omitted with advantage.

The spray-producing device is clearly shown in Fig. 2, where the maindelivery-tube 1 is shown as having a valve-seat formed in its lower endand as pr vided with means of attachment lo a nipple that is connectedio a li(Luni-supplyingpipe. The packing-washer 2, or equivalent means,prevents leakage at the point of attachment. The main conesupport isshown as engaging with the eX- terior of the tube l. by means of ascrew-thread, which serves as a means ot adjusting the longitudinalposition of the said cone-support upon the said tube. The maincone-support is shown as having formed upon its surface a gear-wheelwhose teeth are shown at 4, and

IOO

which engage with the teeth upon the raek 5, that is supported near thesprayiiiig deviee in some Convenient manner. I n the ease illustratedt-he raek is sup]j)orted by the rack-support (i, that is supported uponthe top ot the main delivery-tube l, and iixed thereto by the setserew Ascrew, 7, provided with a cheek-nut maybe used, as shown, to keep therack and the gear upon the main eone-support engaged with eaeh other,and to allow them to be disengaged at will upon retraeting the sei-ew.'hen it is desirable to do so, this raek and gear maybe dispensed withand the main eone-support turned direetly by the.

hand ot' the operator ot' the apparatus.

Upon the bottom ot' the main eone-supljnnt is shown secured theeene-supportiing ringl fl, that provided with the eross-bar l0 and theeentral ring, 1l, in which the spraying-Cone l2 is supported. Thespraying-cone is made so that it detleets the entire amount of liquidthat is discharged alon its surface and dif- :t'uses it into the airbelow and out-side oli' its base, and is loosely supported in the ringll, and is preferably made ot suehan aeute angle that the liquiddetieeted from its surface will not strike the under side ot' theeene-support The eross-bar i() is preferalrly made as shown in Fig'. 7,in order that the spray' may be readily divided to pass the cross-barwithout being splashed about the apparatus. upwardly-sharpened shape ofthe eross-bar is also desirable ou aeeount of the faet that the liquiddoes not issue in streams so mueh asit would were this bar t'orinedotherwise, and I have found it very desirable to prevent, as mueh aspossible, the Yformation oli' sueh streams.

The spray-produeil1g del'leetor l2 is shown as a true eone; but' it isnot necessary that it should be so shaped, sinee the requirements ot'the apparatus 'will be met it' the lower portion thereof, at and belowthe pointy where it touehes the valvesseat in the tube l, be nlade totlare outwardly Yin sueh a manner as to throw the spray outwardly to aconsiderable distanee as it `talls.

I sometimes make use of an air-eliamber that is made up ot' thehalfa'ings l 4, held together bythe serews i123 or other equivalentmeans, one of the hal t'-rings being provided with the pipe l5, thewhole fitting loosely around the main eolie-support itl, which is thenprovided with holes 17, leading` from the interior oli' the air-eliamberto the lower side of the support E3, as shown. A pipe, lli, at,- taehedto the pipe l5, li'orms therewith and with said air-ehambei.' anair-eomluit which leads from the air-chamber to some suitable means ot'supplying lfresh air. In the ease illustrated in. Fig. l the airW isshown as provided by a li'an, 1S, whieh leads air from outside the roomwhere the spraying deviees are placed, and t'orees it through the pipelt) to the pipes liti. The pipes lll should either be flexible oreonneeted to the ring it in sueh a manner that the main e 'n1esu ])]ortf3 will not This l be ilnpeded in its longitudinal motion bythe pipeiti. The lan, the pipe ltr, and the ring` lt maybe dispensed withsometimes, as may also the holes Vl7, while at other times the fan maybe dispenset'l with and the pipe lt) led direetly out oit' the ellam'berin whieh the apw Imratus is plat-ed to a souree ol.l supply ot' treshair. In the lat ter ease the lresh air will be drawn into the splavingdeviee in Considerable amount' by the induetive aetion ol the liquideseaping therel'rom. l

In Fig. l is shown at ISO a slnaying deviee having the holes l7, butwith no means ol' ln'inging air thereto l'rom without the ehamber wherethe apimiratus is plz'tetwla (-ilnistruetion whieh might beadvantageously adopted when the apparatus is to be used in the open air.I do not,lngnvever, usually supply a very large proportion ol' airthrough the holes V17, when emnpared with the total amount whieh shouldbe supplied.

When a number ol these sln'aying deviees are to be used together, asshown in Fig. l, they are preferably screwed Vupon nipples lf that areseeured to a main liqud-sumily pipe, 2t), and, the raeks whieh turn themain eonesi'ipl'torts 3, attached to a bar, 2l, that is pro vided with ameans by which i t may be read-` ily moved longitudinally with respectto the pipe 2t). This means is shown as a segment ot' a gear, 22,supltorteil t'ronl the pipe 20 by the bar 23, and provided Awith thehandle 25.

The mode of operation of this device as follows: The liquid to be eooledis, by some suitable and ordinary means, t'ed into the pipe 20 in sueh amanner as to maintain thtwein a eonsideral'lle pressure. The main een,supports are then revolved su t'tieiently to slightly remove thespraying-omnes l2 l'rom the valveseatsin thebottom ot' the tubes l. The'liquid in the pipe Btl will then tlow out, be del'leeted over the eonesl2, and thereby elian ged Vinto a spray, whiefh will. lall into asuitable tub or vat, 27, placed to reeeive it. lvaporation will at oneebegin when. the liquid leaves the eone l2 and continue until the liquidis materially Cooled; and I have :found that it Vis easy to thusalrstraet enormous amounts ot' heat from het wort i n a very short time.This action is aided by the air, whieh is sometimes l'oretnl through theholes l7 upon the liquid that passes over the surface ol the eone l2.

Should it at any time be desirable to stop the flow ol the liquidthroi'lgh the spraying deviees it may be done by bringing the eonetightly in eontaet 'with the valve-seat in the bottom ot' the tube l, byrotating the main eone-sl'lpiuport in the proper direetion.

In order to make allot' the spraying d eviees elose simultaneously andtightly, 'it' neeessary, they should be ar'ljusted at .tirst by elos'ingthem all beili'ore the raelc o is put Vin plaee. They will then remainadjusted with resl'ieet to eaeh other in operation.

I have found. it desirable to periodieally .tlush these sprayingdeviees, and thus remove any sed iment or solid substanees whieh,4beingl IOO IIO

in the liquid, collect in the delivery-tubes. I do this by quicklyopening the spraying devices quite widely and then quickly bringing themback into the operative position, all when the pipe 20 is full of liquidunder pressure. The sediment is thus blown out and the delivery-tubesleft free. In .order to make certain the proper replacement of the conesafter flushing, I sometimes make use of the adjustable stop QS upon therack-bar 21,011 an equivalent device, which, striking upon somestationary obj ect--the rack-support 29 in the case illustrated-limitsthe motion of the rack and enables the operator to quickly bring thecones to the proper operative posit-ion.

I have sometimes found it desirable to swing the pipe 2O upon its axis afew degrees in order to deliver the liquid nearer the middle of the tub27 than it would otherwise fall, and the structure illustrated in Fig. lis especially arranged to allow ot' this swinging without trouble.

I sometimes place several pipes, 20, with their attached sprayingdevices over a single tub or vat.

I am aware that some parts of my invention may be advantageously usedwith other devices than those which are shown in the drawings; andconsequently I do not desire to limit myself to making my invention inall respects exactly as there shown.

lWhat I claim as new, and desire to secure by Letters Patent, is- Y l.The beer spraying' and cooling device, which consists of a main deliverytube adapted to be attached to a liquid-supply pipe, a main cone-supportoutside the said delivery-tube and adjustable longitudinally thereon, anoutwardly-ilaring deliector at the mouth ot' said delivery-tube, andacross-bar, sharp upon its upper edge and provided with a support forsaid deliector, attached to said main cone-support and held therebybelow said de'lector, substantially as described, and
